We have an extremely old dog who has progressed to the point where grooming is near impossible. He can't hear or see very well,and is a known biter to everyone except my wife. She can do minimal things,like brushing,but beyond that,he will bite her as well. Our vet is not willing to prescribe Ace to him to allow us to groom him/clip nails,because she says it is a liability issue due to his age. I'm sure he is a risky one to sedate at his age,but I also think his quality of life comes before quantity. We want him to be given the meds,and are willing to accept the outcome if it isn't a good one. He is really in need of a shave down and nail trim,and we've asked three vets so far to no avail. Any suggestions? We don't want to put him to sleep. We've tried every groomer between here and Annapolis and he let them all know he will bite-so don't even bother giving groomer suggestions.
